Вычислим log₃2 - log₃2⋅log₂6 + log₃6
log₃2 - log₃2⋅log₂6 + log₃6 = log₃2 * (1 - log₂6) + log₃6 = log₃2 * (1 - (log₂2 + log₂3)) + log₃6 = log₃2 * (1 - 1 - log₂3) + log₃6 = log₃2 * (-log₂3) + log₃6 = -log₃2 * log₂3 + log₃6 = -log₃3 + log₃6 = -1 + log₃6 = log₃6 - 1 = log₃6 - log₃3 = log₂(6/3) = log₃2
Ответ: a) log₃2
